The existence of digital technology in education requires digital literacy so that technology can be used optimally. Self-efficacy and student learning independence are very important for students to support learning. The purpose of this research is to describe the effect of digital literacy skills on students' self-efficacy and learning independence. This research is a type of quantitative research. The sampling technique uses a saturated sampling technique with a population of class XI IPA 1 and 2 MA Futuhiyah Jeketro and data collection uses a questionnaire. Testing the hypothesis using the regression test and test the coefficient of determination. The results showed: 1. Digital literacy skills have an effect on self-efficacy with a significance of 0.001 <0.05 and a large effect of 27.7%; 2. Digital literacy skills affect student learning independence with a significance of 0.031 <0.05 and a large influence of 12%.

Rice fields are man-made soil whose properties are highly influenced by the way it is made and processed. This research was conducted to determine the chemical properties of the soil in various rice fields in Indonesia. The writing of this article is done by analyzing various kinds of related literature obtained from search results on the Google Scholar database. A total of 10 articles are included in this literature study with the data collected focusing on the chemical properties of the soil, namely pH, KTK and C-organic only. With Soil pH: < 4.5 or > 8.5, Soil KTK: Low, < 18 cmol/kg, Medium, ranging from 18 – 25 cmol/kg, Height, > 25 cmol/kg, C – Organic Content: Low, < 2.0 g/100g, Medium, range from 2.0-3.0 g/100g, Height, > 3.0 g/100g Based on the analysis that has been done on 10 journals, it was concluded that there is a significant correlation between pH and high and low content of KTK and C-organic. The amount of KTK is largely determined by soil pH, soil texture and C-organic content.

This research aims to determine the profile of the community structure and diversity of benthic macroinvertebrates in Alam Kandung Waterfall. Sampling was carried out at six stations of ± 100 individuals or stations that use surber net and hand net. Data collection for each station includes the composition and density of each species which is used to calculate taxa richness, abundance, IVI (Important Value Index), and diversity index (H'). The results showed that 37 taxa from 11 classes were found and varied at each station. At the first station, the highest taxa were found with a total of 19 taxa, and the lowest taxa at the second station with 7 taxa. The highest abundance is known at the first station and the lowest at the sixth station. The IVI results show that the first and second stations are dominated by the type of Sulcospira testudinaria which is sensitive to pollutants, and the third station and fourth are dominated by Tarebia granifera and Vellidae. The fifth station was dominated by Corixidae, while Thiara scraba and Atyidae were found in all stations. The results of the diversity index show that the first and fourth are lightly polluted, the second station is moderately polluted and the rest are not polluted. It can be concluded that the quality of waterfalls in Alam Kandung is still in a good category, reflected by the diversity of taxa and the presence of riparian vegetation.
